Opening with an ultra-wide-angle medium-long shot tracking horizontally, the stabilizer moves low to the ground, with a highly contrasting romantic cinematic tone of cold blue night and silvery white starry sky, exuding a strong poetic realism and classical epic temperament. The protagonist is a young woman in a dark green long dress, running with all her might on the garden lawn illuminated by moonlight; her skirt billows in the wind forming surging dynamic curves, she clutches a small white flower in her right hand and lifts the hem of her dress with her left, breathing rapidly yet with a firm gaze. At the 4th second, the camera accelerates forward with her, and multiple men and women in old-era ball gowns break into the frame one after another from the left and right sides in the background, running alongside her—some try to approach, some turn back to shout, yet none truly touch her, implying pursuit and escape. At the 8th second, the camera gradually zooms in to a medium shot, pans to track forward in front of the protagonist and lifts slightly; she glances back briefly at a young male character behind her, their gazes meet for a split second, emotions erupt mid-run, and the woman and man join hands to run together. At the 12th second, the music and movement reach a climax; the camera moves forward close to her side face and fluttering hair, she releases the white flower and tosses it into the air, the flower drifting down in slow motion as the crowd behind brushes past it. In the final 3 seconds, the camera keeps moving forward, the woman and man break through the crowd and dash toward the starry sky at the end of the garden, their figures gradually taking over the center of the frame. The overall atmosphere is fiery, romantic and resolute, a burst of narrative about fate, choice and freedom.

Image-to-video (I2V) is a generative AI technique that brings a still image to life. You provide a picture — a product shot, a portrait, an illustration — and the model generates a video that starts from that exact image and sets it in motion, guided by an optional text prompt.

How it works

In image-to-video generation, your image is used as the first frame — a visual anchor the model must honor. From there, a video diffusion model predicts how the scene should evolve: hair moves in the wind, steam rises from the cup, the camera slowly pushes in. The text prompt no longer needs to describe what things look like (the image already says that); it describes what happens next.

Why start from an image?

Compared with text-to-video, starting from an image gives you something precious: control over the exact look. The composition, the colors, the face, the product label — all locked in from frame one. This makes I2V the go-to mode when:

  • You have brand assets — animate a product photo without the model reinventing your packaging.
  • The subject must be exact — a real person, a real place, existing artwork or illustration.
  • You want predictability — the first frame is fixed, so iterations only vary the motion.

Prompting tips

Since the image handles the "what," spend your prompt on the "how": describe the motion (subtle, dramatic, looping), the camera (static, slow push-in, orbit), and the atmosphere you want to develop. Short, motion-focused prompts usually beat long scene descriptions here. More techniques in our prompt writing guide.

Questions about Image-to-Video (I2V)

What image should I upload for image-to-video?

Use the sharpest copy you have, at the aspect ratio you want the video in. Most models keep the first frame exactly as uploaded, so anything blurry or cropped stays that way in every frame.

Can I control what happens after the first frame?

Yes. The prompt describes the motion, camera move, and audio; some models also accept a last frame or a driving voice track. Leave the subject description out — the image already says it — and spend the words on movement.
